Took me a little while to realize they didn't have them and now that I did I'm suddenly dissapointed as I really liked the gimmick. Seemed like such an easy thing to include

Even the first editions don't have them (which makes me somewhat curious as the figures were allegedly part of generations and the only other generations figures without the clip on points were from the start of the line)

You can still clip them on TFP Cyberverse via the various pegs on their weapons. I think somebody in a Feedback thread had a Cyberverse Bulkhead all tooled up that way.
Not quite what you wanted, but still something.

Pity if they're not on the larger figures though as it's not exactly a hard gimmick to include for. But then maybe some people would complain about more messing with screen accuracy to include clip points.

I like the customizable nature of clip weapons. Some figures benefit from them more than others, though. It certainly adds another layer of playability to them, but I'm glad they opted not to make it a standard feature on every single release.
